Moderately severe head-on collision

If a moderately severe head-on collision occurs the restraint systems control unit (N2/7) registers moderate deceleration via the integrated acceleration sensors. In this type of impact the restraining function of the seat belts in combination with the buckle emergency tensioning retractors ensure the maximum degree of passenger safety. The restraint systems control unit (N2/7) therefore sends an ignition pulse to the following components:

Driver ETR squib (R12/1)
Passenger ETR squib (R12/2)
Left rear ETR squib (R12/6)
Right rear ETR squib (R12/7)

Severe head-on collision

If a severe head-on collision occurs the restraint systems control unit (N2/7) registers extreme deceleration via the integrated acceleration sensors. In this type of impact the airbag and seat belt system restraining functions in combination with the emergency tensioning retractors ensure the best possible degree of passenger safety.

The restraint systems control unit (N2/7) therefore sends an ignition pulse to the following components:

Driver airbag squib 1 (R12/13)
Passenger airbag squib 1 (R12/4)
Driver ETR squib (R12/1)
Passenger ETR squib (R12/2)
Left rear ETR squib (R12/6)
Right rear ETR squib (R12/7)

If also necessary because of the severity of the accident:

Driver airbag squib 2 (R12/14)
Front passenger airbag squib 2 (R12/5)

If, over the passenger seat occupied and child seat recognition sensor (B48) a child seat mounted to the front passenger seat has been recognized, the front passenger airbag will never be deployed.

If the driver seat belt buckle restraint systems switch (S68/3) or the front passenger seat belt buckle restraint systems switch (S68/4) detects that a seat belt has not been fastened, the driver or front passenger airbag is triggered instead of the relevant emergency tensioning retractor at a brought-forward point in time.
